Frequently Asked Questions

Before You Buy

You should only use video converters and extenders if it is absolutely necessary to do so. In many cases, most video converters and extenders are not necessary if you purchase the correct cable.

The following table lists the maximum length of cable for common video standards.

Video standard Maximum length
DisplayPort 50 ft. (15.2m)
HDMI 50 ft. (15.2m)
DVI 50 ft. (15.2m)
VGA 200 ft. (71m)

Note: StarTech.com offers cables longer than what is listed above, including active cables, which typically include built-in active signal boosters that allow for longer cables. Active cables are specifically designed to exceed the suggested maximum lengths and are tested at the listed specifications (for example, the maximum listed resolution).

Video adapters

Video adapters passively adapt a cable from one connector type to another. Video adapters do not change the signal type, or change the video standard.

Examples of common applications for adapters include the following:

  • DVI-I to VGA

  • RCA to BNC

  • Mini DisplayPort to DisplayPort

  • Couplers (female to female, or male to male)

Note: You can use a coupler to extend a cable for a short distance. However, each coupler that you use can introduce signal loss, which degrades the signal quality.

Video converters

Video converters actively process and change the signal type from one video standard and convert it to another standard. They are typically used to convert digital to analog and vice versa, but can be used to convert a digital signal to another digital video standard (for example, HDMI to DisplayPort).

Video converters work over short distances from the source to the destination: up to 15 feet or 3 meters.

Video extenders

Video extenders convert an input signal to a higher voltage for transmission over longer distances and then convert the input signal back to the original video standard. The input and the output signal will match on a video extender, as the same video standard is maintained end-to-end. If a cable is extended with adapters or converters, the signal quality degrades.

Note: For more information on using a video adapter or converter with a video extender, see the following FAQ: http://www.startech.com/faq/video_signal_converters_convert_then_extend.

If you need to use a video extender with a video adapter or converter, you should position the adapter or converter as close to the video source as possible. For example, if you need to take a VGA signal from a computer and send it 200 feet to an HDMI® projector, you should convert the signal from VGA to HDMI and use an HDMI extender.

Note: For more information on when to use cables or extenders, see the following FAQ: http://www.startech.com/faq/video_signal_converters_when_to_convert.

Yes, this video extender works with set-top boxes, provided the set-top box meets the following requirements:

  • The set-top box must be High-bandwidth Digital Content Protection (HDCP) compliant.
  • The set-top box must support devices being connected between the video source and display. If the set-top box requires a direct cable connection between the video source and display, it won't work with this video extender.

No, this device is designed to be a point-to-point solution using networking cabling only. 

This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.

HDCP

When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.
